[0027] The rack 4 slides linearly inside the slide rail 2, driving the sector gear 14 to rotate, thereby adjusting the drill bit direction angle of the drilling power head 5, so as to realize the threading hole processing at different angles of the aluminum tube, and the initial position of the drill bit of the drilling power head 5 will not change when the drilling power head 5 adjusts the drill bit direction angle, thereby improving the drilling processing accuracy.

[0028] like Figure 1 As shown, a tooling assembly 3 is arranged on the top of the workbench 1 , and when the tooling assembly 3 is installing the aluminum tube, the top of the aluminum tube does not exceed the initial position of the drill bit of the drilling power head 5 .

[0029] The height of the tooling assembly 3 and the tooling fixture are detachable and replaceable, which is convenient for processing aluminum tubes with different diameters.
